rovision of an improved method for assem-.

ling upholstering edging upon chair and davenport seats, and elsewhereupon furniture where the same may be desired; the 1nventioncontemplating the use of an edging strip formed substantiall accordingto the method and article described and claimed in my co-pendingapplication, Serial N 0. 265,710, filed March 29th, 1928, and beingattached in a novel and expeditiousmanner upon the seat in asubstantially permanent and shape retaining relation.

Other ob'ects and advantages of this inventionwi be apparent during thecourse of the following detailed description.

In the accompanying drawing, forming a art of this specification, andwherein simiar reference characters designate corresponding partsthroughout the several views, Figure 1 is. a fragmentary perspectiveview, partly in section, showing an initial step in the placing of anedging roll or strip upon a seat.

Figure 2 shows a step succeeding the initial stitchingof the edgingstrip to the seat as shown in Figure 1, with the edging strip bent backover the margin of the chair seat into place. a

Figure 3 shows a step in the method of forming the upholsteredfurniture, succeeding the stepsshown in Figure 2, and comprlsing thestitching of the edging in place about the margin of the chair seat orthe like.

Figure 4 is a transverse sectional view showing how the edging strip isfinally and permanently secured upon the article of furniture, such as aseat, in an edge or mold finishing relation. 4

In the drawing, wherein for the purpose of illustration is shown only apreferred embodiment of this invention, the letter A may enerally desiate any approved article of urniture, pre erabl a seat of a chair,davenport, or the like, 0 any approved and conventlonal formation, uponwhich the improved edging strip B is assembled and attached after anovel method and in a novel relation.

The seat A by way of example, may in clude the rigid framework walls 10,of wood, I

metal, or the like, having connected between the lower edges thereof theordinary interwoven spring supporting strips 11 upon which the spiralcompression springs 12 are su ported, as-in conventional. construction;it eing preferred to place a one-piece covering 12 over the bottomsupporting stri s 11, in manner which is well known. T e

upper part of the seat consists of the ordi nary flexible fabric boxcasing13, peripherally secured at 14 to the top edge of -theframework10, and extending upwardly and receiving therein a shapin frame 16; thebox casing 13 thus includin t e upstanding flexible wall portion 17 romthe top of the rigid framework 10 to the wire shaping frame 16,v andincluding a top flexible seat wall 18, against which the to s of thesprings 12 abut. It is perfectly well understood in the art that thistype of box spring seat'is readily yi'eldable.

The upholstery molding or edging B is preferably of the construction setforth in my co-pending a plication above referred to, the same being 0substantially uniform cross section throughout the len h thereof, andflattened into anv elongate substantially ovalshaped cross section, thesame having an attaching flap 25, formed by the meeting edges cover 26,which ex-.

of the tubular flexible tends laterally from adjacent a side edge 27 ofthe edging B, with a short portion of the longitudinal side of theedging B projecting in an overlap ing relation with the attaching flap25, in or er to properlysecure the edging B at the desired inclinationwhen the same is folded into plosition upon the flexible seat portion 18of t e seat, as is shown in Figure 2 of the drawing. The edging B, ofcourse, has the flexible cover 26 thereof filled with upholstery filling30, compacted and held in shape in a manner set forth in my co-pendingapplication above referred to.

The edging strip B is placed upon the fabric seat cover 18, initially inan inverted position from that which it occupies in the finishedcondition, with the attaching flap 25 flat against the cover 18, a shortdistance inwardly from the marginal edge formed at the juncture of theframe 16, as shown in Figure 1. In this position on it is to be notedthat above the attaching flap a short marginal portion of the ed mg Boverlaps therewith. The attaching ap 25 is longitudinally stitched as atto the seat cover 18, in a secure and eflicient relation, and thereafterthe edging B is swung as a hinge on the fla 25 through an angle ofapproximately 180 rom its inverted position shown in Figure 1 to thefinishing position shown in Figure 2. This ulls the stitching 30 tautand presses the adjacent longitudinal marginal portion of the edging Binto a depressed relation into the flexible cover 18, providin a neatjoint at the juncture of the lower e ge of the edging with the seat 18,free-of abrupt obstructions. It is to be noted that the attaching strip25 is so stitched in a spaced relation with respect to the adjacentparallel frame 16 that when turned to the position which it will occupy,the ed ing' B at the opposite longitudinal edge 0% the attaching flap 25will overhang and extend beyond the ad acent length of the wire frame16, as shown in Figures 2, 3 and 4 of the drawin It is held in thisposition in any approve manner until stitched in a.

permanently secured relation in such posi-' tion.

Referrin to the manner of stitching the improved e ging B'in the finalposition upon the seat or other structure A, the stitchin is moreparticularly detailed in Figures 3 and 40f the drawing, and proceeds inthe direction indicated by thearrows in Figure 3 of the drawing. Thatis, the stitched thread designated y numeral 35 in Fi re 3 of thedrawing is inserted at 36 thru t e wall 17 of the flexible box seat 13,beneath the wall frame 16, and the thread extended beneath the cover 18underneath the edging B, and inserted thru the edgin at 37, coming outon top of'the edgingslig tly spaced from the attaching fla '25, and thestitch thread is then extende transversely across the top of the edgingB, at 38, and the needle then inserted downwardly into the edging aboutone- 1 third the distance from the outer marginal edge thereof, at alocation. 39 and exits at the lower surface of the edging just outwardlyof-the wire frame 16. The needle controllin the stitch thread is thenlooped thru the thread 35 along the outer wall 17, etc, location 41,shown in Figure 3 of the drawing, and the thread drawn taut to ull theprevious stitch tight, and the need e is then inserted at a location 36into the box .seat wall 17, and another stitch formed as abovedescribed; the thread length 42 between the stitches being drawn tightand interlinked at the locations 41. In this manner the edging B isstitched permanently into position along the edge of the seat, with thestitch threads secured to the fabric box seat 13 and embracing the frame16, all of which secures the edging in a very durable and eflicientrelation upon the seat, so that the same cannot readily become displacedfrom the proper edge extending position.

" Various changes in the steps of the method 'of edge upholsteringfurniture, as well as an inverted positlon u on a furniture baseadjacent a marginal e ge thereof,securing the edging strip, while insaid inverted position, along a longitudinal edge thereof to the base,reverting the edging strip by swinging it along the attached edgeuponthe base towards the adjacent marginal edge of the base until theside of the edging strip abuts a surface of the base, and securing theedging strip in this position upon the base to provide a marginaledgingfor the'base.

2. The method of edging furniture which consists in placing upholsteringedging on a su port to be edged, a short distanceinwar 1y from the edgeof the'support so as to expose a marginal portion of the support,longitudinally stitchin the adjacent edge of the edging facing saimarginal portion to the support, and turning the edging into anoverlying engagement with said marginal portion of the support andstitching the same thereto into a secured edge finished relation aboutthe margin of the support.

3. In the method of upholstering furniture the steps which consist institching an edging strip along a longitudinal edge thereof to a seatcover in spaced relation from the edge of the seat cover, overturningthe edging with stitching acting as a hinge into overlying relation uponthe margin of the seat, and transversely stitching the edging to thecover.

4. The method of edge upholstering seats and the like which consists inproviding a stuffed edging strip having a substantially flattened crosssectlon andrhaving a lateral attaching flap at a side thereof betweenthe,

ends but close to one mar 'nal edge thereof, stitching said attaching awhile the edging strip is inverted with t e attaching flap facingsaid'margin of the seat, to the seat 1 tion with said seat margin, andsecuring the I same in said position.

5. The method of edge upholstering seats and the like which consists inproviding astufi'ed edging strip having a substantially flattened crosssection and having a lateral attaching flap at a side thereof betweenthe ends but close to one marginal edge of the seat, stitching saidattaching flap, while the edging strip is inverted with the attachinging the edging in place by means of transverse loop stitchestransversely of the edging intersecting thru the seat material, withconnecting threads below the edging and exteriorly about a side of theseat.

7. In the method of placing upholstering edging upon seats the stepswhich consist in the placing of flexible stuffed edging upon a flexiblespring supported box seat in an inverted position in marginally spacedrelation from the corner edge of the seat, closely stitching the edge ofthe edging which faces the margin of the box seat to the box seat, re-

' versing the edging by swinging upon the stitching as a hinge intooverlying relation with the margin about the box seat, and stitching theedging in this position to the margin of the box sheet. a

8. In the method of placing an upholstery edging upon a supportingsurface, the steps which consist in placing a flexible stuffed piece ofedging upon a supporting surface in a normally inverted posit-ion,longitudinally securing the piece of edging along one 7 side thereof tothe supporting sur ce, swinging the piece of edging thru an aresufficient to substantially reverse the piece of edging to a normalrighted position with a longitudinally secured portion acting as a hingeduring such swinging, and securing the piece of edging in engagementupon the supporting surface in its righted position.
